1. Log on to the websites of major banks. If the website has a credit card page, you can see the preferential activities.

2. In the envelope of the monthly bill, there will also be colorful pages of bank preferential activities.

If you are a credit card holder, the general bank will send you a text message, but only if you contact your mobile phone number.

4. Go to the bank and ask about the recent activities directly.

I hope I can help you.
